As a striker, Ernesto Valverde amassed 68 goals in 264 games in La Liga in a 14-year professional career, which included a spell with Barcelona as part of Johan Cruyff's 'Dream Team'.
Valverde coached Athletic Bilbao’s B team in 2002 and was promoted to first-team boss the following year. In 2006 he led Espanyol to the UEFA Cup final before joining Olympiacos two years later.
He left Athens for Villarreal to replace Manuel Pellegrini in 2009, but was sacked the following year and returned to Olympiacos. Valverde joined Valencia in December 2012 but departed Mestalla six months later before being named Athletic boss in succession to Marcelo Bielsa.
He promptly guided Athletic to the Champions League group stage for the 14-15 campaign, which also spawned a Copa del Rey Final.
Although they lost to Barca in the latter, Valverde and Los Leones exacted sweet revenge as they beat the Catalans 5-1 on aggregate to win the 2015 Supercopa de Espana - their first major trophy in 31 years.
The 53-year-old's teams generally play in a 4-3-3/4-2-3-1 formation, exhibiting a high-pressing and possession-based style synonymous with that of the Blaugrana, and tend to incorporate homegrown players.
